I like what SOUNDGUY has. Its good to have both ON and FLASH positions... Pretty convient having the box mounted on the trailer tongue where your trailer cable is located. Just plug it into the box and operate the switch for RUN or FLASH... Pretty neat...
One other point when ordering parts is to be sure you get the BLADE TYPE 7-WAY RECEPTACLE as that is what will mate to the connector on the TRAILER cable end.
They also sell PIN type connectors and plugs. You want the BLADE TYPE for the RV's - the same type that is on the back of your truck...
ETRAILER.com will be a good source for these items.
